Six Nuveen Closed-End Funds Announce Availability of 19(a) Notices

CHICAGO--(BUSINESS WIRE)--The 19(a) distribution notices for six Nuveen closed-end funds are now available. These informational notices provide further details on the sources of the funds’ regular quarterly distributions and follows the most recent quarterly distribution announcements. The full text of these notices is available below or on the Nuveen website via Distribution Source Estimates.

Important Information Regarding Distributions

September 30, 2025: THIS NOTICE IS FOR INFORMATIONAL PURPOSES ONLY. NO ACTION IS REQUIRED ON YOUR PART. If you would like to receive this notice and other shareholder information electronically, please visit www.investordelivery.com if you receive distributions and statements from your financial advisor or brokerage account. An electronic copy of this notice is also posted under distribution notices at www.nuveen.com/cef.

This notice provides shareholders with information regarding fund distributions, as required by current securities laws. You should not draw any conclusions about the Fund’s investment performance from the amount of this distribution or from the terms of the Fund’s Managed Distribution Policy.

The following table provides estimates of the Funds’ distribution sources, reflecting year-to-date cumulative experience through the month-end prior to the latest distribution. The Funds attribute these estimates equally to each regular distribution throughout the year. Consequently, the estimated information as of the specified month-end shown below is for the current distribution, and also represents an updated estimate for all prior months in the year. It is estimated that all funds have distributed more than their income and net realized capital gains; therefore, a portion of the distributions may be (and is shown below as being estimated to be) a return of capital. A return of capital may occur, for example, when some or all of the money that you invested in the Fund is paid back to you. A return of capital distribution does not necessarily reflect the Fund’s investment performance and should not be confused with “yield” or “income.”

The amounts and sources of distributions reported in this 19(a) Notice are only estimates and are not being provided for tax reporting purposes. The actual amounts and sources of the amounts for tax reporting purposes will depend upon the Funds’ investment experience during the remainder of its fiscal year and may be subject to changes based on tax regulations. Each Fund will send a Form 1099-DIV for the calendar year that will tell you how to report these distributions for federal income tax purposes. More details about each Fund’s distributions and the basis for these estimates are available on www.nuveen.com/cef.

FORWARD LOOKING STATEMENTS

Certain statements made in this release are forward-looking statements. Actual future results or occurrences may differ significantly from those anticipated in any forward-looking statements due to numerous factors. These include, but are not limited to:

• market developments;
• legal and regulatory developments; and
• other additional risks and uncertainties.

Important information on risk

Past performance is no guarantee of future results. All investments carry a certain degree of risk, including the possible loss of principal, and there is no assurance that an investment will provide positive performance over any period of time. Certain products and services may not be available to all entities or persons. There is no guarantee that investment objectives will be achieved.

Closed-end funds frequently trade at a discount from net asset value (NAV). At any point in time, including when sold, shares may be worth more or less than the purchase price or the net asset value, even after considering the reinvestment of fund distributions. It is important to consider the objectives, risks, charges and expenses of any fund before investing.
